The first image to be a reference image by receiving the video signal of the image stored in the image storage unit 13 under the control of the control unit 14 and the deviation from the image stored in the image storage unit 13 with respect to the image input after According to the control of the motion detection unit 12 for detecting the motion, the image storage unit 13 for receiving and storing the first image to be the reference image from the motion detection unit 12 and the controller 14 in advance Transferring an image (still image or video) or image / audio currently input to the CCD camera 11 to a mobile communication terminal (IMT-2000 terminal, etc.) 18 or a wired terminal (image phone, PC, etc.) 19 Transmitter 15 and movement It is connected to the branch 12 and the transmission unit 15 and moves to transmit a video (still video or video) or video / audio currently input to the CCD camera 11 by calling a preset phone number according to motion detection. The control unit 14 for controlling the detection unit 12 and the transmission unit 15 is provided.

Looking at the operation of the mobile communication terminal according to the present invention.

When an image (video or still image) is transmitted in units of frames through a camera 11 using an imaging device such as a CCD, the reference image stored in the image storage unit 13 by the motion detector 12 under the control of the controller 14. The previous image and the current image input through the camera 11 are compared (scene switching, etc.) to detect movement of an object (moving body) by using a difference in signal levels between frames. In this case, one of the known motion detection algorithms is used for motion detection.

Looking at each component in more detail, the control unit 14 detects the movement of the image through the CCD camera 11 and the signal through the distance sensor 17, such as sound and infrared sensor through the microphone 16, and the like. It collects and collects and judges external intrusion etc. collectively. In addition, when the control unit 14 determines the external intrusion, it transmits a video or video / audio by calling a terminal (wireless telephone, video telephone, PC, etc.) of a preset telephone number through the transmission unit (modem) 15. do. In this case, the controller 14 compresses the current image using the image compression technique and transmits the current image to the transmission unit 15 when the motion is detected. In this case, the image data may be changed according to the transmission situation, and if a large amount of transmission is a problem, the image data may be generated as a still image and, in some cases, as a moving image.

In addition, the camera 11 may be configured to attach an infrared filter to a solid state imaging device (CCD) camera so that object identification may be performed at night.

Then, the motion detector 12 digitally processes the image screen of the camera 11 and compares it with the previous screen (reference image) stored in the image storage unit 13 to recognize this as a movement of an object. .
